About Our Cooranbong Service
Your Local HVAC Expert in Cooranbong
Cooranbong is home base for Lilac Air Conditioning — Gary Lui lives and works here, which means response times in Cooranbong are as fast as it gets. It's a quiet, leafy community in the Lake Macquarie hinterland, popular with families and retirees who value the semi-rural lifestyle while staying connected to the Central Coast and Newcastle.
The hinterland setting means Cooranbong properties can experience significant temperature swings — hot summers and cooler winters than the coast. A well-sized, properly installed air conditioning system makes a real difference to year-round comfort here. Gary provides the full range of residential HVAC services to Cooranbong and the surrounding hinterland suburbs.
Local Climate Note

"We had four air conditioners installed and couldn't be more satisfied. From the initial quotation to the final installation, communication was always prompt and professional. The installer arrived on time, worked diligently, and ensured everything was installed to a high standard. Excellent workmanship and very reliable service."

"Gary came out to my place on pretty short notice and did a great job on maintenance on our ducted system. He's a friendly polite guy and his offsider was great as well — very reasonable price and tidy work. I'll definitely recommend Lilac HVAC and re-engage them for future work."

"Very impressed with Gary from Lilac. He arrived on time and was very professional. The job didn't take long at all and our new AC unit has taken the edge off this winter. Highly recommend."
